Efficient Sound Card Based Experimention At Different Levels Of Natural Science Education
Sound cards, which count as standard equipment in today's computers, can be
turned into measurement tools, making experimentation very efficient and cheap.
The chief difficulties to overcome are the lack of proper hardware interfacing
and processing software. Sound-card experimentation becomes really viable only
if we demonstrate how to connect different sensors to the sound card and
provide suitable open-source software to support the experiments. In our talk,
we shall present a few applications of sound cards in measurements: photogates,
stopwatches and an example of temperature measurement and registration. We also
provide the software for these applications.Comment: MPTL-HSCI 2011 Joint conference, 15-17 September 2011, Ljubljana,
